We used CrystalDiskMark 8‘s custom settings to test the 4K random write performance of the drive through a range of queue depths. The setup for the tests is listed below.
Transfer Request Size: 4KB, Outstanding I/O: 1-32.
Officially Corsair's 1TB MP600 Core Mini is rated at up to 900,000 IOPS for 4K random writes. Using our 4-threaded tests we fell a long, long way short of this mark, the best we saw was 244,180 IOPS (1,000.15MB/s) at QD16.
4K Random Write v QD Performance comparison
Even though our best test result is a long way off the official figure, at QD1 it's the third fastest 1TB class consumer Gen 4 drives we've tested to date. But as the queue depth deepens the drive falls rapidly down the results chart.
